But needed a modification to work with my mags - Butler Creek .22 LR Pistol Magazine Loader & Unloader

Used the cardboard from the shipping box to modify and add spacers to the inside of the mag loader.. now mags slide right in and are held snug with the spacers.. otherwise they would just move around too much in the loading process.
Pros: Easy operation
Cons: Had to mod with spacers
